PAC Radio Replacement Interface for Select 2000-2013 GM Vehicles

I have just installed this device in my 2005 Chevy Tahoe. So far this has worked excellent. Fairly simple to wire up, makes the steering wheel controls work perfectly. Has the leads for the reverse gear for a backup camera already(this wire was not the same color as the wire out of my new head unit, it was labeled correctly but different color). Will allow you to retain the rear seat controls, and the audio for the factory DVD player. I set the chime to volume 3 and it sounds good. This is somewhat bulky and does take some work to push all of this into the dash of the Tahoe. My system has factory Bose amp, and for some reason in my mind when I was connecting all the wires I did not connect the amp lead wire out of the head unit. I assumed that since it was a factory install it wouldn't require that connection. When I connected this I had all functions, but no audio. One quick call to PAC fixed me up. They knew exactly what I had done, and was about a 1 minute conversation with the tech guy. Would definitely purchase this again.

Mind you this is short term I just installed the item but wow everything was so good about it. The instructions were extremely clear and good. The steering wheel controls were retained as I wanted. The sub also works without issue. I left the chime unplugged as I don't enjoy annoying sounds for reasons. Onstar also works even though I wish it didn't. Very well packaged good instructions and quality materials. The price is high but it comes with everything you will need. I use wagos for ease of instal and troubleshooting. I have wired a few radios with them and can definitely recommend.

Used for my 03 Escalade Put in an alpine Ilx-w670 head unit. Factory sub works fine it was kind of odd the fade function doesn’t work if I fade the volume to the rear speakers it goes silent but if I center the fade all speakers work and sound great. Also I had to do some searching online to make the steering wheel controls work because for what ever reason I had to change the pin setting to universal instead of alpine specific. Anyways it works great.

I would give this 5 Stars but there is no troubleshooting guide...anywhere. I utilized this interface with a Clarion NX404 on a 2004 Yukon. I took the time to direct solder the wires and use heat shrink for solid connections. The prep time took just over an hour to solder all the NX404 connections with the GM11 harness. One crucial step in this process is the cutting of a brown wire loop on the GM11 to connect to the NX404 harness. If you are using this combo, leave the loop alone!!! Once the prep was complete, the GM11 easily plugged into the factory harness. I made one mistake of plugging in the SWI into the MIC input. I quickly corrected and had steering wheel controls. Everything powered up correctly. The biggest mistake which took me almost two hours to troubleshoot was no audio due to the brown wire. The GM11 had the harness plugged into factory amp setting for the Bose system. The NX404 powered on fine and went through all setup but I had no audio or volume control as well as a small speaker icon with an "X" over it beside the Bluetooth icon on the display. Two hours later, without any good troubleshooting threads, I realized the stereo was "muted" and cut the brown wire. After restarting the device, I had full audio. My recommendation is to solder all wires for any aftermarket HU but leave the brown wire alone until you've tested everything. I now have Bluetooth audio, Pandora working fine, nav system, full audio, steering wheel controls and have use the handsfree option for phone calls. Everything works well with no static, no issues, no problems. I did pre-wire the backup camera input but have not installed one, so I get a blank screen when I go into reverse (future project). I did not do any "bypass" as I don't intend to push video while driving.

Worked perfectly paired with the Sony XAVAX1000 in a C6 Corvette. Received the newest version of the PAC module (black box with blue accent *see review photo*) instead of old PAC module (Blue box) which I originally thought i was going to get. Not a bad thing and I’m not complaining, was a great surprise. Pros - Closest I’ve gotten to plug and play, only a few wires to solder (can be crimped) and Bobs your uncle. - Diagrams for wire connections are available and guide on how to find those is included. - Paired with the Sony XAVAX1000, sound quality is excellent, no crackling, popping, electric noise etc. Con - Radio receiver antenna did not fit the new radio BUT I already had the correct size from a previous upgrade. Check the sizes and lengths you will need on that antenna (as if anyone upgrades their radio to actually use the “radio” and not AppleCarPlay, AndroidAuto, Bluetooth etc….)

Let me start by saying I have a 2005 Cadillac Escalade EXT with a stock Lux Bose amp and Bose speakers. You can confirm if you have the Lux Bose amp by checking for Y91 in your glove box parts list. This PAC unit was nothing but problems from the start. With everything connected properly, half the speakers would either not work or would be super quiet. The speaker fading ability is also non-existent - you lose that from factory stock. However, the MOST ANNOYING PART of this piece of crap PAC audio unit is that it has issues triggering the Lux Bose amp on start up. SOMETIMES but not every time, there would be no sound when I start the truck. The ONLY way to fix it was to turn the truck off and back on, needless to say it was extremely annoying. The only thing I could think of to fix this was to bypass the PAC box and wire the amp directly into the stock connector but that would require cutting into my factory wires and why should I have to do that when I purchased this product? I had contacted PAC audio and you guessed it, they never emailed me back. I ended up purchasing the Metra Axxess instead. With this unit, the speakers actually function as they should, the speaker fade works, dimming is possible (another thing you lose with the PAC unit is your stock dash dimming - with PAC you literally go backwards from STOCK instead of having something better - its ridiculous!), last but not least there is a SYSTEM REMOTE CONTROL (blue) wire to hook the amp to. This finally resolved the issue with the sound sometimes not coming on with startup. The Metra costs more because the steering wheel controls are separate but boy is it worth it. It actually functions and retains everything. Your speakers will actually emit sound and you won't have to deal with amplifier problems. Not to mention on the PAC unit the plugs don't even snap in, they fit in loose which causes even more speaker issues. DO NOT BUY THE PAC IF YOU HAVE A LUX BOSE AMP, BUY THE METRA AXXESS!!! Save the headache and learn from my experience.

i have used them in the past ,,even though i did not need it and returned ,radio came with all equipment needed ,but if you need they do work well with gm cars and trucks

This has helped me maintain steering wheel radio controls with ease. Installation was a breeze after following install instructions of course as am not a radio expert just a diyer

Wow, increible, mantiene todos los controles y el sonido exactamente igual que si fuera el estereo de agencia, yo le instale uno de marca JBL, que intensifica los sonidos y esta interfaz es increible, algo que no debe faltar, además mantiene toda la originalidad del vehiculo, sin cortar y sin adaptar NADA.

Bon produit mais délai de livraison trouve important à mon goût

Fonctionne très bien! Manque un peu d'explication pour l'installation, mais avec quelques recherches sur internet, j'ai pu l'installer sans aucuns problème. Seul chose c'est que, avec ce produit, vous perdrez la fonction des écouteurs pour le lecteur DVD pour les passagers arrière.

Great replacement part and works well.

Se recibió en tiempo y forma y funciona perfectamente
